In IT since 1995: from software developer through test and project management to leading international IT teams. Many years in logistics and postal automation (warehouse control, material flow, letter sorting centres), and in financial services (insurance) since 2018. Focus areas are IT organisation and processes, data integration, cloud migration, DevOps and regulatory implementation (DORA, BaFin reporting). In my own projects I build applications with Claude Code as my coding agent.
